CORS and S3 Simply Explained (The Theory) | Cross-Origin Resource Sharing | AWS Training

Amazon’s Simple Storage Service (S3) can be used to host static websites (check out this video for more: • AWS Project: How to Cr... ). But as you’re building your website, you might come across problems with Cross-Origin Resource Sharing, or CORS. CORS defines how you share resources across domains.
In this video, I explain CORS with a real-world analogy for how we communicate with other people, then review what makes up a “domain.” From there, I walk through an S3-specific example, showing how an HTML page in one S3 bucket can interview with an HTML page in a second bucket.
If you want to check out hands-on demo for how to implement this in S3, check out this video: • Enabling CORS on an S3... .

Oh, what a nice comment!! Thanks so much! 🙏🤓🌟

You have the best AWS Tutorials and the way you explain them is EPIC!!

[@TinyTechnicalTutorials]

I love EPIC! 😊 Thanks so much for watching!

It is really a great video. Thank you so much for sharing the knowledge in such a easy way. I have seen several other videos, but this one video was really useful.

[@TinyTechnicalTutorials]

That's so nice of you! Thanks for taking the time to drop a comment! 🙏🥰🙏

Thanks for this! Wanted to brush up on CORS before my Security Specialty exam later this morning!

[@TinyTechnicalTutorials]

Yay! I'm glad it helped! If you get any questions on the exam, they'll most likely test whether you know that CORS has to be enabled on the cross-origin server (the place you're making the request to). Good luck...you got this! :)

Thanks for the video. The sound is off a bit. I am not sure what the issue is, but it impacts the quality of what you are saying. It is challenging to listen to the video, even though the content is great.

[@TinyTechnicalTutorials]

I appreciate the feedback, Lida Lida! I can't remember the recording setup I had for this video (I record in a few different places), but I've been working on some acoustic treatments to get rid of a little bit of reverb. Hopefully it'll be better going forward. Thanks for watching! 😊

[@Blowjin]

Thanks! It wasn't work for me without protocol/port. This is a key, very helpful.

[@TinyTechnicalTutorials]

Ooh, good to know! Thanks for posting this...hopefully it'll help someone else! 💪😊
